## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mx-data-helper-web-extract-29081779 -d '<json body>'
```

Example prompt: Can you extract all the readable text from this page for me: https://example.com/article/some-news-story

## When to prefer this

Choose this endpoint when you need to quickly extract readable text from a single public URL and are operating in an x402/Base mainnet payment environment. It is well-suited for lightweight, per-call web text extraction tasks where you do not need full browser rendering or structured data parsing. The pay-per-call micro-payment model ($0.002 USDC) makes it cost-effective for occasional or low-volume scraping without subscription overhead.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status
- Payment not processed — insufficient USDC balance on Base mainnet
- URL points to a non-HTML resource (PDF, image, binary file) that cannot be text-extracted
- Page requires JavaScript rendering and content is not available in static HTML
- Request times out for slow or large pages
- Malformed or invalid URL provided in the request body
